/**
 * Real-runtime behavior proof for #73706.
 *
 * This script does NOT use vitest mocks. It wires up the production
 * `deliverOutboundPayloads` path against:
 *   - a real `PluginRegistry` populated with one real channel plugin and
 *     two real plugin hooks (`message_sending`, `message_sent`)
 *   - the real `getGlobalHookRunner()` / `initializeGlobalHookRunner()`
 *     singleton path (no fake hook runner)
 *   - the real `setActivePluginRegistry` channel resolution path (no
 *     fake channel adapter)
 *
 * It then exercises three scenarios:
 *
 *   1. Direct outbound delivery with `session.key` set: confirms the
 *      `message_sending` and `message_sent` hook contexts both receive
 *      the canonical `sessionKey`.
 *
 *   2. Direct outbound delivery with NO session: confirms `sessionKey`
 *      is absent from both hook contexts (the "narrowed" docs branch).
 *
 *   3. Native-redirect simulation: outbound delivery whose `session.key`
 *      is set to the redirect TARGET session (i.e., what the agent
 *      runtime resolves as `params.sessionKey` when
 *      `CommandTargetSessionKey` is set and `CommandSource === "native"`,
 *      and what `dispatch-from-config.ts` now passes through to
 *      `routeReply`). Confirms `message_sending` / `message_sent`
 *      observe the redirect-target session, NOT the inbound session.
 *      This is the runtime invariant Clawsweeper asked us to pin
 *      with a regression test.
 *
 * Run with:
 *   pnpm tsx scripts/proof-73706-message-sending-session-key.ts
